JBL Protemp E500 External Heater

This in-line heater is seamlessly integrated into the hose of your external aquarium filter, eliminating the need for a heater placed inside the aquarium.
Installation is a breeze: simply cut the hose that returns water from the external filter to the aquarium, insert the external heater in the gap, plug it in, and adjust the water temperature to your preference.
Its integration within the filter circuit guarantees an exceptionally uniform water temperature distribution, with an accuracy of +/- 0.5 °C and a switching interval of 1.0 °C in the aquarium.

The device features an LED display that shows both the current and target temperatures. It comes with interchangeable hose connections compatible with 12/16, 16/22, and 19/25 mm hoses, complete with hose locks. The total length of the heater is 30.5 cm.

Included in the package: 1 in-line heater rated at 300 W, suitable for aquariums ranging from 90-300 liters (80-120 cm), along with hose connections for 12/16, 16/22, and 19/25 mm and a cleaning brush.
